The HSC series chain hoist is an upgraded manual lifting equipment based on classic models, with "compact body, low clearance design, and high braking stability" as the core highlights, suitable for multi scenario power-off operations. The body is made of thickened alloy steel, which is integrally formed and resistant to impact and collision. It is equipped with a hand zipper wheel cover with a folded edge design, and can maintain smooth operation even when operated diagonally. Internally equipped with quenched and refined high-quality alloy gear sets and needle roller bearing guide chain wheels, the mechanical efficiency is high and the hand tension is light. The double guide wheel structure effectively avoids chain jamming problems.
